JOSEPH McMAI-ION, OF CHICAGO, ILLINOIS, ASSIGNOB F ONE-HALF TO ELLEN E. MQMAHON, 0F CHICAGO, ILLINOIS.

CAR-BUMPER.

Application ied August 14, 1915.

T0 all "whom it may concern:

Be it known that I. JOSEPH McMAHoN, a citizen of the United States, and a resident of the city ot' Chicago. county o'l' (look, and State of Illinois, have invented certain new and useful Improvements in Car- Bumpers, of which the Jfollowing is a speci` fication.

My invention relates to improvements in car bmnpers and more especially to improvements in the form of car bumper' illustratcd in my prior patent granted August 1G, 1898, No. 609,159, the object ot the invention being to provide an improved construction ot the character noted which is strong and durable in use and capable of economical production.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure l is a side view of a bumper construction embodying my invention. and Fig. 2, a top plan view of the same.

The preferred form of construction, as illustrated in the drawing, comprises two end rails 3 which are arched centrally, upwardly and inwardly to form arches 4 secured to the sides of a bumper 5 of any usual or desired construction. The opposite ends of the arches 4 are made identical in form and shape so that each arch member is readily interchangeable for the other, that is, it is not necessary to provide a differently shaped member for each arch as is necessary in the construction disclosed in my said prior patent. Straight rails 6 are arranged within the ends of the arches adjacent the inner sides of the end rails 3 and are bolted to said end rails at each end by means of bolts 7, distancing blocks 8 being interposed between said rails as indicated. Braces 9 are secured at their lower ends to the central portion of each of the straight rails 6 adjacent each other and diyerging thence upwardly and inwardly` the upper ends of said braces being secured to the corresponding arch 4 by bolts which extend also through the body of the bumper, as shown. This constitutes a very rigid and durable bracing construction for the arches.

Specification of Letters Patent.

Patented Feb. 8, 1916.

Serial No. 45,454.

Clamping bars 10 are extended between the rails 3 and 6 at each end o the arches therein, said clamping bars being clamped to both adjacent rails B and G, as indicated and serves to properly distance said rails and further secure the same together.

lVhile l have illustrated and described the preferred form of construction for carrying my invention into eTect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Haring described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination of track end rails arched centrally, upwardly and inwardly, both ends ot the arches being identical so as to be interchangeable; and a bumper supported on said arches, substantially as described.

2. The combination of track end rails arched centrally, upwardly and inwardly, both ends of the arches being identical so as to be interchangeable; straight rails laid within the ends of said arched rails and secured thereto; and a bumper supported on said arches, substantially as described.

3. The combination of track end rails arched centrally, upwardly and inwardly, both ends of the arches being identical so as to be interchangeable; two braces secured at their lower ends adjacent each other, diverging thence upwardly and inwardly and secured at their upper ends to the corF responding arch; and a bumper supported on said arches, substantially as described.

4. The combination of track end rails arched centrally, upwardly and inwardly, both ends of the arches bein identical so as to be interchangeable; straight rails laid within the ends of said arched rails and secured thereto; two braces secured at their lower ends adjacent each other to each straight rail, diverging thence upwardly and inwardly and secured at their upper ends to the corresponding arch; and a bumper supported on said arches, substantially as described.

The combination of track end rails arched centrally, upwardly and inwardly,

ffl

hoth ends of the arches hein identical so as to be interchangeable; straight rails laid within the ends of said arched rails and secured thereto; two braces secured at their lower ends adjacent each other to each straight rail, diverging thence upwardly and inwardly and secured at their upper ends to the corresponding arch; clamping bars eX- tending between said track end rails at each 1U side of said arches and clamping Said end and straight rails together; and a bumper supported on said arches, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH MCMAHON.
